SPECIFIATION forming part of Letters Patent No. 748,740, dated January 5, 1904.

Application 'and' August 8.19032 'sect1 Nt. 1681693. uti modem .To a/ZZ whom it may con/cern.-

Bo it known that I, WILLIAM L. JAooBY, a citizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car-Couplers, of which the fol- Couplers of this general type are illustrated 2o in the patents to William S. Schroeder andv Deyo, No. 412,879, and Schroeder and Lindhelm, No. 509,104. `I-Ieri-:atofore in this socalled Chicagocoupler it has been customary to employ a separate pivotpin at .the

z5 extremeinner end of the longitudinal lockingbar to connect it to the draw-bar and keep it in positionA and prevent it from being removed and becoming lost, the pivot-pin itselff` requiring a key or other fastener.

3o The object of my invention is to provide an improved construction whereby the pivotal,

longitudinal locking bar may be pivotally connected to the draw bar and at the same time kept in position and prevented from acV cidental displacement when in operation without requiring the use of a separate pivot-pin and its key, thus lessening the number of parts and simplifying the construction of the.

coupler.

' 4o My invention consists in the means I emthe locking-bar to be inserted in and removed 'from the saddle by two movements, one longitudinal and the other downward, when the free or outer end of the locking-bar is lifted, while at the same time preventing the removal or displacement of the rear or pivot end of the locking-bar from the saddle of the draw-bar, except by the double movement above mentioned and when the outer end of thev locking-bar is in its uppermost position. Thecoupling-pi-n and other parts of the coupler cooperate to prevent the lock from having the two movementsV necessary for. the removal of its pivot end from the saddle of the draw-bar, except when the coupling-pin itself is first removed. While my invention thus obviates the necessity for employing a sepal part of this specification, Figures 1 and 2 are vertical longitudinal sections of a car-coupler embodying my invention, showing the parts v in dierent positions. Fig. 3 isaholrizontal section. Fig4 is a cross-sectionon line 4 4 of Fig. 3. Fig. is a detail perspective view of the coupling-pin, and Fig. 6 isa detail vertical sectional view of the longitudinal locking-bar.

In the drawings, A represents thedraw-ba'r; A', the forkeddraw-head, having the customary pivot-arm A2 and guard-arm 3.

B is the knuckle pivoted to the draw-head by the pivot-pin C and having the tail B', which is engaged by the longitudinal pivotal locking-bar D, which fits and lies in the chatn ber a of the draw-bar.

. F is the coupling-pin by which the free or The longitudinal locking-bar D rco is provided at its rear or pivotal end with' pivot-lugs d dand also with a'curved nose d and a curved rear end or guide d2. The drawbar A is providedinside the chamber a, on its lower web or oor with saddles or ribs ct', having pivot notches or recesses 0,2 therein to receive the pivot-lugs d at the rear end of the locking-bar, and it is also provided with a curvedv guide-rib a3, projecting downwardly from its upper Web and which fits above the curved guide or rear end of the locking-bar D when the same is in position in the saddle. The curved guide a3,the saddle,and thecurved guide or rear end d2 and nose d of the lockin g-bar are preferably shaped about as illustrated in the drawings and coperate together to prevent the locking-bar being displaced or removed from the saddle, except when its front end is disconnected from the couplingpin and except by then rst lifting the free end of the locking-bar upward and then giving its rear end rst an upward and then a longitudinal movement, thus withdrawing its pivot-lugs from the saddle-notches,which are also shaped to coperate with the curved guides a3 on the drawhead and d2 at the rear end of the locking-bar. The lower web or oor ofthe draw-head is provided with a slot or recess a4 to receive the curved nose d of the locking-bar.

The locking-bar D is provided at its front end with a chamber d4, having an opening d5 large enough to receive the head or shoulder j' on the coupling-pin F, and provided with a slot d to receive the web f', which connects the head or shoulderf with the coupling-pin F. The locking-bar is provided with a projection CF, which engages a projection a5 on the draw-bar and serves as a guide.

I claim- 1. In a car-coupler, the combination with a pivoted knuckle and forked draw-head, of a draw-bar having a chamber to receive a longitudinal pivotal locking-bar, and provided with a pivot-saddle and a curved guide-rib above the pivot-saddle, of a longitudinal pivotal locking-bar, having integral pivot-lugs fitting in the notches of the saddle and provided with a curved rear end and nose coperating with the saddle and curved guide of the draw-bar to keep the pivotal locking-bar in position and prevent its removal, except by two movements, one upward and the other outward, when the free end of the lockingbar is lifted and disconnected from its coupling-pin, and a coupling-pin removably attached to the free or outer end of the lockingbar, substantially as specified.

2. In a car-coupler, the combination with a pivoted knuckle and a forked draw-head, of a draw-bar, a pivotal locking-bar lying lengthwise in the chamber of the draw-bar and a coupling-pin detachably connected with the free end of the lockingbar, said draw bar having au integral pivot-saddle for the rear end of the locking-bar and an integral guide above the pivot-saddle, and said locking-bar having integral pivot-lugs and a curved rear end cooperating with said guide, on the drawbar to prevent removal except by two movements, substantially as specified.

3. The combination with apivoted knuckle, and a forked draw-head and draw-bar, of a locking-bar pivoted in the chamber of the draw-bar at its rear end, a coupling-pin detachably connected with the free or outer end of the locking-bar, said draw-bar having an integral pivot saddle furnished with pivotnotches, and provided with an integral guiderib above the pivot-saddle, and said lockingbar having a pivot-lug at its rear end and a curved guide and nose, substantially as specied.

4. The combination with apivoted knuckle, a forked'draw-head and draw-bar, of a pivotal locking-bar extending lengthwise in the chamber of the draw-bar and provided with a chamber d4 havingan opening d5, a slot d6 and a coupling-pin F having a head or shoulderf and webf to detachably connect the same with said locking-bar, said locking-bar having also pivot-lugs CZ (Z and a curved rear end or guide cl2, and said draw-bar having an integral pivot-saddle (1, and a curved guiderib a3 above said pivot-saddle, substantially as specified.
